I say afr 205's. They worked so good on the 346 that I re used them on the 402. The numbers speak for themselves. Power under the curve is absolutely phenominal. According to the graph, I say that because the car is still at LGM. I haven't actually driven it yet. Just been told to be prepared to re learn everything I know about my car, because she's insane. 400+ rwtq from 2500 to 6700 rpms, that says a lot. Good street car.

 

If I go over there i'll test it out for you

 

Thanks man ^^^^^^^^^^^^^^^^

 

Flip a coin, both are amazing. I am going with TEA prepped Trick Flows when I do my shortblock.

 

Anyone consider the trick flow 220 'fast as cast'? for LS1? You save about $700 vs the 215 CNC'd version. There aren't many posts on these heads.

 

I bought a set to use on my FI build. They come with the chambers CNC'd to your spec. I went ahead and did some port work on mine. The flow sheet that came with them shows 316 CFM @ .550 on the intake 242.2 on the exhaust
303.3 CFM @ .600 intake and 245.8 exhaust. I cleaned up the casting flash and blended the area where the pocket transitioned into the port. I think they're a good value.

 

yeah, why did you guys decide to make this a tfs vs afr thread when the guy is really wanting more info on tea heads. anyways afr's are a high velocity head and it going to make great street power, low end torque and high rpm power from 205cc. tea does make great quality heads, hand polishing the combustion chambers, exhaust ports and deburring the heads. there a 225cc head which is why they flow so great, maybe low end power is hurt but still make good power.
